Hi, I wonder how feasible is the folowing:
I have a regular expresion like:
REGEXP = "^((1|20)|(13|3|4)|(5|6))"
There are 3 matching groups:
- (1|20)
- (13|3|4)
- (5|6)
I want to match the RURI user, let's suppose $rU = "138787686223". In this case the above regexp matches groups 1 and 2, but since group 2 matching is longest ("13" is longest than "1") I want to get value 2.
In case $rU = "999999" I need to get "null", in case $rU = "1000022323" I need to get "1".
AFAIK there is no way to do it with current regular expression utils in Kamailio, but maybe I miss something. Thanks a lot.
one option that comes in my mind is to break it in several if conditions, matching one group at a time, written in the order of preferences.
Cheers, Daniel
